88° on Nov. 12, 2002, the hottest reading for this week of the year since 1956. Next is 86° in 1957.
Hortense’s center stands about 60 ft above sea level. Within three miles the land runs from 40 ft to 90 ft, a difference of 50 ft: nearly flat ground.
Under the town center the state geologic map shows Penholoway shoreline complex - marsh and lagoonal facies (fine-detrital), from the Pleistocene, less than 2.6 million years old.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Fine-detrital. Age: Pleistocene, less than 2.6 million years old. About 8 mi of the line.
Sand. Age: Pleistocene, less than 2.6 million years old. About 6 mi of the line.
Fine-detrital. Age: Pleistocene, less than 2.6 million years old. About 5 mi of the line.
Fine-detrital. Age: Quaternary, less than 2.6 million years old. About 2 mi of the line.
Sandstone, claystone. Age: Tertiary Neogene, 2.6 to 23 million years old. About 2 mi of the line.
Fine-detrital. Age: Pleistocene, less than 2.6 million years old. About 1 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Hortense reaches the Atlantic Ocean by way of the Satilla: about 100 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Hortense; river miles along the main stem, rounded.
Hortense has a hot desert climate. Summer afternoons average 91° in July; winter nights fall to about 37° in January. Barely 0.0 inches of rain fall in a normal year.
On November 14 Hortense normally reaches 71° and falls to 45°. The record high is 84°, in 2018; the record low 26°, in 2010. The most rain on this date, 0.63 in, fell in 1957.
Normals 1991–2020 and records since 1956 at Nahunta 6 NE, 5 miles south-southeast. NOAA, through RCC-ACIS.
